Shurmur's father was a factory worker for 49 years in the suburbs of Detroit.[3] Shurmur's parents twice refinanced the family home so Fritz and his brother could have opportunities to attend Albion College.[3]
Shurmur became a graduate assistant at age 22 in 1954, under Albion head coach Morley Fraser. After receiving his master's degree in education administration in 1956, he stayed at Albion as a defensive coordinator.[5] In 1962, Shurmur moved to the University of Wyoming as a defensive coach under first-year head coach Lloyd Eaton, who was promoted following the departure of Bob Devaney for Nebraska. The Cowboys won three consecutive WACtitles (1966–1968), which included a Sugar Bowl appearance after the 1967 season. Following a 1–9 season in 1970, Eaton resigned and Shurmur was promoted to head coach;[6][7] he had a 15–29 (.341) record over four seasons (1971–1974).[8]
Throughout his career, Shurmur was widely known as an innovative mind on defense. Shurmur's coaching style was revered by peers in his profession for defensive genius. For example, in 1992 with the Cardinals, Shurmur had to devise a plan when two linebackers were injured. He developed a "Big Nickel" defense, that used five defensive backs close enough to the line of scrimmage to rush the passer or drop back into coverage.[2]
Shurmur became defensive coordinator for Green Bay in 1994 under head coach Mike Holmgren; in his third season with the team in 1996, the Packers won Super Bowl XXXI over the New England Patriots in January 1997. When Holmgren accepted the dual roles of head coach and general manager with Seattle in 1999, Shurmur went with him as defensive coordinator. That May, he was diagnosed with esophageal and liver cancer; he died at his Wisconsin home in late August, before ever coaching a game with the Seahawks.[1]
